山西临汾地区的丘陵阶地,长期以来干旱缺水、土质脊薄、耕作粗放、产量不稳不高,这部分农田占该地区耕地的40％。为了改变这些地方的农业生产条件,需要发展农田灌溉。本文针对这一问题,经过几年的试验研究,从丘陵旱地发展灌溉的必要性、可行性、灌水技术选择、经济效益等方面进行了综合分析,提出了应以输水管道化和水池调蓄为主,充分利用当地小水源,采用节水型灌溉技术,并实行限额灌溉。
The hilly terraces of Linfen in Shanxi Province have long been in arid and dry conditions, with ridges and thin soil, extensive cultivation and unstable yields. This part of the farmland accounts for 40% of the arable land in the area. In order to change the conditions of agricultural production in these places, it is necessary to develop farmland irrigation. In this paper, aiming at this problem, after several years of experimental research, the necessity and feasibility of developing irrigation in hilly drylands, the feasibility of irrigation technology, economic benefits and other aspects were analyzed comprehensively. Mainly take full advantage of the local small water sources, the use of water-saving irrigation technology, and the implementation of the limit irrigation.
